Hello,

I need to calculate capacity/hardware requirement for number of agents in POM.

In avaya POM documents a Sizing tool is mentioned, can anyone help me getting this tool?

This is mentioned on support site:
Open the SizingTool.html file in a web browser.
Type the required number of telephony ports and the system information.
Click Calculate.
The sizing tool displays the number of servers required to provide the system capacity

Question is how to get this SizingTool.html file? or if this is some URL can someone please provide complete URL?

The sizing tool is available from the Avaya Sales and Partner Portal.

You should contact your Avaya Business Partner or Avaya Sales representative.
They have access to the tool and can run the numbers for you.
I hope this helps.
